Sk183 elog depth

  1. 1. Deciding on depth of penetration in SK183 well By comparing natural gamma data logs acquired from TCGS and ELOG tools
  2. 2. Example #1 Slide 3: Gamma data of TCGS Slide 4: Gamma data of ELOG Depth: 172m-177m
  3. 3. Possible end of penetration with non-variant data values received
  4. 4. Max. resistivity readout @11500Ohmm Comparable point to that of TCGS
  5. 5. Example #2 Slide 6: Gamma data of TCGS Slide 7: Gamma data of ELOG Slide 8: ELOG raw data shows tool’s penetration depth Depth: 175m-181m
  6. 6. Too consistent data. No variation in values. Possible end of penetration
  7. 7. ELOG tool still penetrate thru’ with valid data values
  8. 8. Penetration depth with last good data values No variation in values
  9. 9. Conclusion <ul><li>Depth of penetration TCGS tool ~176m* </li></ul><ul><li>Depth of penetration ELOG tool ~193m* </li></ul><ul><li>Depth of drilling by Prima Utilities is 201m </li></ul><ul><li>*Final well’s depth is determined after log processing </li></ul>
